Split Core Current Transformer for Safe and Flexible Current Measurement

The DP2 Series Split Core Current Transformer (CT) is designed for non-intrusive AC current measurement in power distribution and industrial systems. Unlike traditional closed-core CTs, the split-core structure allows installation around existing conductors without disconnecting the circuit, making it particularly suitable for retrofit projects and system upgrades.

With rated input options ranging from 50A to 6000A, the DP2 series supports applications from branch circuit monitoring to high-capacity main feeder measurement.

Electrical Performance and Technical Specifications

To meet different monitoring and protection requirements, the DP2 Split Core CT provides:

• Rated input: 50A / 100A / 200A / 500A / 800A / 1000A / 2000A / 3000A / 4000A / 5000A / 6000A
• Rated output options: 0–1V (voltage output) or 0–5A (current output)
• Accuracy class: 0.1 / 0.2 / 0.5 / 1.0
• Multiple structural models: DP2-23, DP2-46, DP2-58, DP2-88, DP2-510, DP2-614, DP2-812, DP2-816

The 0–1V output version is well suited for data acquisition systems and intelligent monitoring platforms, while the 0–5A output meets conventional protection and metering interface requirements.

Key Applications

DP2 Split Core Current Transformers are widely used in:

• Power distribution panels and switchgear
• Energy management and smart metering systems
• Electrical fire monitoring systems
• Industrial automation and motor protection
• Commercial and industrial building power monitoring

They are particularly suitable for projects requiring quick installation, minimal downtime, and flexible current range selection.

Structural and Installation Advantages

Openable Split-Core Design
The hinged magnetic core allows installation without cutting cables or shutting down power systems. This significantly reduces installation risk in operating facilities.

Accurate and Stable Measurement
High-permeability core materials ensure consistent output within the specified accuracy class, supporting reliable signal transmission to monitoring and protection equipment.

Wide Current Coverage
From 50A small circuits to 6000A main lines, one product series supports multiple power system configurations.

Compact Structural Options
Different DP2 models provide various window sizes and outline dimensions, enabling flexible installation in confined electrical cabinets.

Safe and Efficient Retrofitting
The split-core mechanism minimizes operational interruption and improves overall electrical safety during upgrades.

Installation & Maintenance

Installation steps are straightforward:

• Open the split core structure
• Position it around the conductor
• Secure the locking mechanism
• Connect the secondary output (0–1V or 0–5A) to the monitoring or protection device

The solid mechanical design and insulation structure ensure long-term stability and low maintenance requirements, typically limited to periodic inspection of wiring and fastening integrity.
